Original application filed August 22,

The present invention is primarily concerned with .the method of making-metal.

above identified includes hollow panels which I consist of two relatively thin sheets of bendable metal having their edges turned over andwiveldedftogether sofas to eliminate the.

usual bead, affording panels .of uniform thickness to closely snnulate the appearance of a wooden bed end.

- The present invention relates, particularly to. the novel method used in manufacturing the panels, particularly the method by which I form hollow wing panels tosuplement the head and foot boards, such wing panels be ing of transverse curvature and having pref erably a Icompoundly curved upper edge. The method preferably consists. in bending. the two panel sheets. to conform to'a curved template turning the edges of the sheets over the "edge of the template hammering down fthe turned over edges to render the excess metal inconspicuous, welding the edges together and polishing off the weld to render the'same practically unnoticeable.

The invention may be better understood from the following descriptioninconnection v with the accompanying draw ngs, wherein Figure 1 is-a fragmentary perspective View of the bed; 1 g

namely the head piece and the foot piece of a metal bed and forpurposes of illustratiolnl have shown merely a single end piece which for convenience of description may bet-om! sidered as an upright foot piece.,.

pair ofhollow legs 10,10 mounting betweelr thema hollow metallicpanel 11 which cone stitutes the foot board. The foot board may i be suplemented by the use .of a pair of rear-, wardly curving wing portions 1.2.and int-he event the latter are used,;legs 13,13 would be employed to assist thelegs 10 insupportingthenu The present invention, resides primarily in the novel method of forming thesethree pane els. In forming the footboard panel I take a pair of metallic sheetsll, l1 of approxie mately similarsize and of the correct shape and inter-pose between them, a fiat template having an upper edge of the general curvature indicated in the drawings. Theside edges ofthe'sheet 11" are folded around the side edges of the templateinto abutting re lationship with thefiat face of the sheet 11" thereby forming spacer flanges 14. The up; per edgesof both sheets aref'olded over the curved edge of the template, hammered downand welded together at 15 along the median line of the template edge. This operation leaves the. lateral edges of the sheet "11 extending beyond the turned in edgesiofuthe other sheet as indicated at 16. The template may be removed through theopen bottoni the legs to strengthenthis 'frictionalunion.

pane1,I-I may "employ a-closure stripw19 formedat opposite edges with turned over beads 21 which anay embrace'and-be welded notches 21 in the posts and at the edges of the slot 17. If desired, a hollow transverse apron 26 fitting snugly against the under face of closure strip 19 may connect the legs immediately below the panel and serve an additional strengthening brace. The turned over edges 27 of the plates forming the apron may be overlapped if desired, but need not be welded since their union is ordinarily concealed.

The method of forming the curved panels for the end wings involves certain additional operations because of the longitudinal curvature of the template 22 on which they are formed and the compound curvature of the upper edge of such template. The two plates or sheets of metal 12, 12", used in forming wing panels are cut to proper shape and then bent longitudinally by a hammering opera tion in order to properly conform them with the longitudinal curvature of the template. The side edges of plate 12 are bent around the edges of the template to define spacer flanges and the upper edges of both of the sheets folded over the curved upper edge of the template. This folding operation is completed by a hammering operation using the template as an anvil and flattening out the turned over upper edges of the sheets in so far as possible, so that the excess metal at the upper edges is in large measure concealed or rendered inconspicuous. The turned over upper edges of the sheets are then welded together in the manner above described and the template withdrawn through the lower end of the panels. Supplemental closure strips 23 and aprons 24 similar to those associated with the main panel may be employed to finish the assembly and lend an attractive appearance to the bed. It will be understood that the wing panels are frictionally fitted into slots in the supporting legs and soldered thereto as indicated at 25.

Both the foot board panel and the wing panels may be embossed in any appropriate manner to enhance their attractive appearance and may be given a finish which will simulate the grain of an ordinary wooden panel.

My panel of double thickness is of sufficient strength to resist bending and isof a thickness which will correspond closely to the thickness of a wooden panel. The somewhat unsightly bead commonly employed at the upper edge of the panels and which is an unmistakable indication of the metallic nature of the bed is entirely eliminated. The lines of welding at the top of the'panels may be finished and polished in various well known ways so that they are quite inconspicuous. The double panels in themselves have a very desirable heat insulating effect which is particularly useful in case the bed is arranged so that one of its ends is close to a window or radiator. This heat insulating ellect may be supplemented if desired by filling the hollow panels with an asbestos or similar heat insulating material.

It is quite obvious that the shapes, sizes, and curvatures of the panels are entirely optional with the manufacturer and that any shapes and terms demanded by the trade might be made in accordance with my improved process.

It will thus be seen that there is herein described a method in which the several fea tures of this invention are embodied, and which attains the various objects of the invention and is well suited to meet the requirements of practical use.

As many changes could be made in the above method, and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

Having thus described my invention what I claim as new and desire to secure by Letters-Patent is:

1. The method of forming head and foot board panels for metal beds which consists in inter-posing a template between two sheets of bendable metal, folding the edges of the sheets around three sides of the templates and joining. certain of said edges together and then withdrawing the template through the open side edge of the hollow panel thus formed.

2. The method of forming head and foot board panels for metal beds which consists in interposing a template between two sheets of bendable metal folding the side edges of one sheet around the template to form spacer flanges, folding the upper edges of both sheets around the edge of the template until they abut in edge to edge relationship, welding said abutting edges, and withdrawing the template through the open bottom of the panel.

3. The method of forming foot board panels for metal beds which consists in interp osing a longitudinally curved template having a curved upper edge between a pair of sheets of bendable metal, curved in accordance with the curvature of the template, folding the side edges ot one sheet around the side edges of the template to form spacer flanges, folding the upper edges of the two sheets over the upper curved edges of the template, hammering such edges to conform to the curvature of the edge of the template and welding the folded over portions of the sheets into a unitary structure.

4. The method of forming a sheet metal structure which consists in interposing a template having a curved edge between two Ttl sheets of bendable material, folding the ends of the sheets upon the curved edge of the template joining said ends together and then Withdrawing the template.

5. The method of forming'asheet metal Ward against the compoundly curved end of the template until they abut in edge to edge relationship, Welding said abutting edges and withdrawing the template away from the welded edge for removal thereof from the open end of the structure opposite said welded joint thereof.
